This activity introduces students to the visible light spectrum, and demonstrates what happens to the appearance of an image when certain wavelengths of light are blocked by filters or made visible using special tools. Students are lead through experiments with light and filters, demonstrating th

Water Walk

In this field activity, students conduct a visual survey of a hydrology study site, and collect information about land cover and water quality. These observations are used to stimulate research-able questions about land cover and water chemistry that can be the focus of future investigations.

Searching for Life on Mars
